3 Claims. 1

In the package dyeing of yarn it has heretofore been common practice to employ a Franklin spring as a carrier for the yarn. This device comprises a tubular spring over which a sock of knitted cloth is placed for holding the yarn out of the recesses in the spring but allowing circu lation of the dye liquor through yarn carried on the spring. Yarn packages wound in this manner on Franklin springs are adapted to be placed in a dye machine for the conventional package dyeing operation. A, troublesome difficulty with this type of yarn carrier, however, is that it is not adapted for easy unwinding of the dyed yarn, so that it is necessary to transfer the dyed yarn from the spring type carrier to a paper cone or the like from which the yarn may be withdrawn in a satisfactory manner for use in subsequent operations.

Prior attempts have been made to avoid this additional Winding step in handling the dyed yarn by using a perforated cone as the carrier for the yarn instead of the tubular Franklin spring. Such a cone requires adapters or spacers for engaging and aligning the adjacent cones when they are stacked vertically in the dye machine. These spacers or adapters have raised practical difiiculties because they tend to imbed themselves in the wound yarn package at the respective ends of the superimposed packages so as to prevent uniform dyeing of the yarn at those points and to cause physical damage to the yarn.

In accordance with the present invention I have devised a means for avoiding the previous difiiculties encountered when it was attempted to use a perforated dye cone, and in that respect my invention comprises the use of internal bushings made integral with the perforated cone at the top and bottom ends thereof. This produces a single unit cone with bushings adapted to fit the winder apparatus for winding of the undyed yarn on the cone, and to fit the spindles in the dye machine used for dying of the yarn on the cone. Accordingly, this cone does not require'spacers or adapters or any extra attachments in either the dyeing or winding operations and the internal integral bushings do not damage the yarn or impede the dyeing operation.

The integral bushings may be permanently attached to the respective ends of the perforated cone, on the inside, by any suitable procedure such as by welding; or these bushings may be rolled or drawn or stamped as an integral part of the cone when the cone itself is formed. These bushings located in the cone at the top and bottom thereof, are of such size and shape that when the cones are stacked on end the large or bottom end of one cone forms a seal with the small'end of the next cone and thus causes the dye liquor to be forced up through the yarn. Also, these bushings are formed to fit over the dye machine spindle carrier in such a manner that the cones are easily removable but are snug enough to effect a good fit on the carrier.

The cone of this invention may be made of any suitable material, such as for example metal, wood, plastic, or resin impregnated paper. Examples of commercially advantageous metal materials are stainless steel, Monel metal and magnesium alloy.

A typical but nonlimiting example of the improved dye cone of my invention made of metal, is illustrated in the accompanying drawing in which:

Fig. 1 is an elevational view of the perforated dye cone;

Fig. 2 is a longitudinal sectional view through the cone shown in Fig. l and illustrates the integral bushings at the top and bottom of the cone;

Fig. 3 is an elevational view of the cone of Figs. 1 and 2 and a fragmentary view of two other cones illustrating the manner in which the cones may be stacked vertically one upon the other; and,

Fig. 4 is a bottom end view of the cone shown in Figs. 1 and 2.

The dye cone in which comprises a tapered tubular body formed with a suitable pattern of perforations H, is fitted with a top bushing as shown at l2 in Fig. 2. This top bushing H is in the form of a cylindrical ring I3 which is made integral in some suitable manner such as mentioned above with the adjacent wall portion M of the cone Ill. The cylindrical ring l3, although integral with the tapered dye cone In at its top end, has a true cylindrical inner surface. This top bushing I2 serves as a bearing surface for the dye cone It] on the dye machine spindle and on the winder spindle.

The bottom or larger end of the dye cone Ill is also provided with an integral bushing as shown at l5 in Fig. 2. This bottom bushing l5 comprises a head cap l6, which has a cylindrical bore of the same internal diameter as the ring ii of the top bushing l l, and thus provides a lower bearing surface for the dye cone Ill on the winder spindle and dye machine spindle. This lower bushing I4 is also formed with a recess or bore of larger diameter as shown at I! for engaging the smaller top end of an adjacent dye cone l0 so as to provide a seal therewith when the cones are placed one on top of the other in a dye machine, as illustrated by the cones l0, I8 and I9 in Fig. 3.

For smooth, uniform winding and especially unwinding of yarn on the perforated cone H], I have found that it is important to exercise control in the taper of the cone. In commercial use of this con'e, a taper of about 1.1 inches per foot to 1.5 inches per foot is advantageous and I have obtained especially good results with a taper of approximately 1.24 inches per foot.

As will be understood from the foregoing description the cone of this invention is a single integrated unit which is adapted to be used as a carrier for the yarn wound thereon, and which may be fitted directly on a winder spindle or on the conventional dye machine spindle and requires no extra attachments of any kind when on the winder or in the dye machine.

Some of the novel features of the cone of my invention are defined in the appended claims.

I claim:

1. A yarn carrier for package dyeing of yarn comprising a cone having a plurality of perforations extending through the wall of the cone for passage of dye liquor therethrough, and internal, integral bushings at each end of the cone having cylindrical surfaces, the cylindrical surface of re integral bushing at the top smaller end of the cone being adapted to provide a bearing surface for a winder spindle adapter and for the dye machine spindle, and the integral bushing at the bottom larger end of the cone having a head cap forming a cylindrical surface with the same internal diameter as said top bushing to fit said winder spindle and dye machine spindle, and having a larger diameter recess for receiving and engaging a portion of the cone surface at the top smaller end of an adjoining cone and thereby effecting a seal between the cones when two such cones are nested.

2. A perforated cone adapted to serve as a carrier for yarn wound thereon for package dyeing and for unwinding of the dyed yarn directly from the package, said cone having integral bushings at each end of the cone and each bushing having a cylindrical surface adapted for fitting of the cone on a dye machine spindle and also adapted for providing a seal between cones when one cone is stacked upon another, and said cone having a taper of 1.1 inches per foot to 1.5 inches per foot.

3. A cone as defined in claim 2 in which the taper of the cone is approximately 1.24 inches per foot.
